Rails                  
                                          
                                          
  
                                          
  
                                          
                                          
 Trains  Are  So  Constructed  That  They 
 Have To  Follow A Set Path. This Path Is 
 Called A "Railway",  Which  Is Comprised 
 Of Two Metal Rails,  Hence Its Nickname. 
                                          
 Because  The  Low  Friction  Between The 
 Wheels Of The Train And The Rail  Metal, 
 There Are Limits For  How  Acute A Curve 
 Can  Be, And Even More  So For How  Much 
 The   Ground  Under  The  Rails  Can  Be 
 Sloped. Thus A Railway Is Often Not  Led 
 On Top Of Hills,  Rather Through Them In 
 TunnelS   (If   They   Are  Large),   Or 
            Artificial ChasmS.            
                                          
 There Will Be Trees On The Side  Of  The 
 Rails, But  Not Too  Close, Or They Will 
 Be  Cut  Down By The  Railway  Janitors. 
 There Will  Be  Plains,  And  Bodies  Of 
                  Water.                  
                                          
 Trains  Go By  Day  And By  Night. Along 
      The Way, There Is Information       
 Scattered,  Often  Put On Top  Of Poles, 
 To Be  Interpreted By The Train Drivers. 
 Different  Parts  Of  The  Railway  Have 
          Different Speed Limits.         
                                          
 Sometimes, Trains Have To  Stop And Wait 
 For Something To Happen,  Far Away. This 
 Is  Signaled  By  Red  Or Green  Lights. 
                                          
                                  
                                          
 Many  People  Follow  The Rails By Foot. 
 Often  This  Proves  To  Be The  Shorter 
 Path Between  Two  Points.  However This 
 Is   Frowned  Upon,  And  Very  Impolite 
         Toward The Train Drivers!
